Definitions

  • the invention relates to a hand-held machine tool for introducing cuts, comprising a drive motor for at least one cutting tool and a contacting device, by which the hand-held machine tool is adapted to contact an object to be machined and is guidable on the object.
  • the invention further relates to a method of adjusting cut introduction options in a hand-held machine tool for introducing cuts.
  • Hand-held machine tools for introducing cuts are used for example to produce masonry wall slots.
  • a hand-held machine tool which is universally usable.
  • the drive motor is disposed in a lockable pivotable manner relative to the contacting device, wherein at least one pulling position for pulling introduction of a cut and at least one pushing position for pushing introduction of a cut is adjustable.
  • Hand-held machine tools are known, which are guided by pulling in order for example to produce a slot. Equally, hand-held machine tools are known, which are designed such that they may be used to introduce pushing cuts. Horizontal slots are introducible by pulling usually only with great difficulty and vertical slots are introducible by means of pushing cuts only with difficulty.
  • a hand-held machine tool with which it is easy to switch over between the option of pulling cut introduction and the option of pushing cut introduction. This switchover is effected by pivoting the drive motor relative to the contacting device.
  • the introduction of pulling cuts and pushing cuts is allowed, depending on which the user selects.
  • the hand-held machine tool is therefore universally usable. In a single hand-held machine tool the possibility of introducing pulling cuts and pushing cuts is realized.
  • the hand-held machine tool according to the invention may be of a simple construction; in particular, there is no need to provide for a reversal of the direction of rotation of a tool shaft.
  • the contacting device is disposed or formed on a tool protection cap.
  • This allows the corresponding hand-held machine tool to be of a compact construction.
  • the tool protection cap and the contacting device are movable relative to one another; in this way it is possible for the at least one cutting tool to be positioned in a protected manner in the tool protection cap and lifted out for machining articles.
  • a pivot bearing for the pivotability of the drive motor relative to the contacting device which has a pivotal axis that is substantially coaxial with an axis of rotation of a tool shaft.
  • the change of position of the drive motor relative to the contacting device therefore does not affect the tool movement, i.e. regardless of whether a pushing position or drawing position is adjusted, the tool drive is not modified.
  • a tool protection cap has to be provided in order to protect the operator from the rotating cutting tool.
  • the tool protection cap provides a suitable carrier for a pivot bearing.
  • At least one gripping element is disposed or formed on a tool protection cap.
  • an operator may grasp the hand-held machine tool in order to be able to introduce a pulling cut or a pushing cut, depending on the position of the drive motor.
  • the at least one gripping element is electric insulation, which insulates the at least one gripping element electrically from metal regions of the hand-held machine tool. It is therefore possible to guarantee the electric safety of the hand-held machine tool, for example for the eventuality that an electric connection cable is cut through.
  • the electric insulation may be disposed directly on the gripping element or it may be disposed for example between a tool protection cap and the rest of the hand-held machine tool. It is for example also possible for the tool protection cap itself to be manufactured from an electrically insulating material.
  • the at least one gripping element is formed by means of a hand contact region on the tool protection cap.
  • This hand contact region is in particular provided with grip protection, such as for example with pimples, to prevent slipping.
  • the hand contact region is of such a dimension that the hand of a user does not come into contact with metal regions of the tool protection cap when he grasps the hand contact region.
  • the at least one gripping element is formed by means of a bow-type handle. This projects in particular beyond the tool protection cap. An operator may place one hand around a bow-type handle. It is also possible for a gripping element to be formed by means of an extraction elbow. As an extraction elbow projects beyond a tool protection cap, a construction as a gripping element is possible.
  • a distinguished pulling position for the drive motor is lockable.
  • a pulling cut may be introduced.
  • an operator uses his right hand to grasp a motor housing of the drive motor and his left hand to grasp a gripping element on a tool protection cap and pulls the hand-held machine tool.
  • a distinguished pushing position for the drive motor is lockable.
  • an operator for example grasps the drive motor with his left hand and places his right hand on a gripping element on the tool protection cap. He may then push the hand-held machine tool away from him in order to be able to introduce a pushing cut into the object to be machined.
  • the distinguished pulling position and the distinguished pushing position are situated apart from one another by a pivotal angle of more than 90°.
  • the angle in said case is smaller than or equal to 180°.
  • a motor housing is orientated at an acute angle to a contact surface of the contacting device in order to achieve a greater distance between the operator's hand, which is grasping the motor housing, and the article to be machined; in this case, the pulling position and the pushing position are situated less than 180° apart from one another.
  • a motor housing is provided, which is graspable by the operator. He may then use one hand to hold the hand-held machine tool at the motor housing.
  • a motor housing is positioned at an acute angle to a contact surface of the contacting device. This allows the adjustment of a distance or increased distance between a gripping region of the motor housing and the contact surface and hence, during machining of an object, the object to be machined.
  • a motor housing is positioned at an acute angle to a contact surface of the contacting device.
  • a pulling position is easily fixable when a first blocking element is provided for supplying a blocking surface for a distinguished pulling position of the drive motor.
  • the first blocking element has a blocking surface that is inclined relative to a contact surface of the contacting device. By means of the blocking surface a pivoting of the drive motor beyond the pulling position is blockable.
  • a second blocking element is provided for supplying a blocking surface for a distinguished pushing position of the drive motor and in particular the second blocking element has a blocking surface that is inclined relative to a contact surface of the contacting device.
  • the slotted disk may be a separate disk or it may be integrated into a shaft of a pivot bearing for pivoting of the drive motor relative to the contacting device.
  • the slotted disk is disposed for example in a rotationally fixed manner relative to a gearhead or motor housing.
  • the slotted disk has a first slot for defining a distinguished pushing position and a second slot for defining a distinguished pulling position. It is therefore easy to secure these distinguished positions and easy to effect a switchover between these distinguished positions.
  • a locking element is provided, which is engageable into a slot of the slotted disk to secure a specific pivoted position.
  • the locking element secures the pushing position and/or the pulling position. The securing effect may easily be cancelled by withdrawal of the locking element.
  • the locking element is spring-loaded.
  • the locking element may therefore be pressed into a slot in order to fix the corresponding position.
  • By exerting a force counter to the spring action, the corresponding position may be unlocked.
  • the slotted disk is disposed between the drive motor and a tool protection cap.
  • the appropriate space is provided, in which the slotted disk and the locking element may be positioned.
